IMPnovsD MACHINE ron MIXING ANDIIIEDING WHITE LII-inn.

To ALL WHOM IT MAY ooNoERN:

Be it known that I, JOHN HASLETT, Jr., of' the city of Allegheny, in the county of Allegheny, and State of Pennsylvania, have invented a new land useful machine for mixirig the carbonate of lead with water or'oil, O and for feeding the same to the stones by which it is ground at a uniform rate, and called a WhiteLead Mixer full, clear, and exactV description of the same, reference being had to the annexed drawings, making part of this specilication, and to the letters of reference marked thereon, in which- Figure 1 is a vertical central section of my machine through the section line A B of iig. 2, and

Figure 2 is a top view of the same.

The nature of my invention consists inconstructing a machine which, being driven by steaml or other power, thoroughly incorporates the carbonate of lead with water, when. the same is to be ground with water, or with oil 'when ground with oil; and in combining with this mixers machine, also driven by machinery, for delivering the mixed water and lead, or eiland lead, to the stones, by which it is ground at a .uniform rate; the whole machine being so constructed and arran cred as to supersede the present laborious and unsatisfactory a process of mixing the carbonate of lead with water or oil by hand, and of feeding the mixture to the stones m the same-manner, z'. e., by hand, which requires the constant attention of .one or more persons.

To enable those skilled in the art to makeand use my inventio and operation.

C, figs. 1 and 2, is a tank; D, the bottom of the same; E, upright shaft; F, coupling of Athe same; G G, curved arms; H'H H, 85e., perpendicular blades l'or arms; I I I I, frame.; K, water-pipe; L L', gauge=cocks5 V, discharge-pipe; M, feeder; N, bar, to which the stationary blades are attached; O O O". 0^, stationary blades; P P P, arms, to which the revolving blades of thc feeder are attached; R R' R shaft; T, bevel-gear wheel; V, bracket for the 4support of theshaft S.

My machine may be constructed of any suitable material which will resist the action of the acid which is f my machine which require to be built of metal, and which are likely to come in contact with the carbonatelof lead, I use brass, as'being the least affected by the acid containedV in the carbonate of lead. The tank C is built of wood, of any desired capacity,"and a discharge- Pipe, V, With the gauge-cock L, both of which are of. brass. The bottom D is also of brass. .Through this bottom the shaft E passes, carrying the curved arms G G. To these arms the upright blades H H, Btc., are attached. These blades are so arranged that those' on one ar A but cut oneof their owi1 through the mass to be stirred, as shown by the red arrows in iig. 2.

The shaft E is revolved by thepower applied through the shaft which is attached at F, fig. 1. .Water is admitted through the pipe K. The tank is supported on the frame I`I, &c. .The feeder is placed under the discharge-pipe V. I make this feeder entirely .of brass, and o f convenient size. The blades O O" O 0 are stationary, and reach almost to the bottom of the feeder. They are' secured to the cross-bar N, and are placed revolving blades; S,

inthis position toprevent vthe contentsof the feeder from assuming a rotary motion. The arms P P P are attached to the shaft Sand are driven by it. Each carries a Y perpendicular blade so placed `as to pass between the bladesO O O. The vunder sides of thes e arms revolve close to the bottom of the feeder, and force the mixture through the h ole in the bottom closed by the gauged cock L, from which it falls into the stones, where it is' ground. The shaft S rests on a pivot in the bottom of the feeder, and is supported by the bracket V at its upper end, or in a journal-box fastened to some part of the building in which the machine may beset up. The feeder is driven by the power which is applied through the gear-wheel T. Two or more of these feeders may be attached to the same mixer, which is placed between the stones in such a position as to bring the feeders in the proper position over the stones.

Operation'.

theuncorroded lead mixed with it on being taken from the and suicient water. added to it from the water-pipe. The revolu- After the carbonate of lead is separated from corrodng-bed, it is thrown into the mixer,

n, I will proceed to describe its construction tions o the arms carrying` the blades H H, 85e., mix the carbonate of lead and the water thoroughly together, reducing them to a homogeneous mess.Y When suiiiciently mixed, the muss isdrnwn olia into the feeder as required, fresh carbonate of lead und water being added from time to time to that in the mixer. The gaugeeock L'inthe feeder being correctly set, the feeder needs no further attention than to'see that it is supplied from the mixer when necessary, but delivers the carbonate of leadto the stone at u, uniform rate, which could not be attained when the same work was done by hund. The working of themaehin when mixing the carbonate of lead with oil is substantially the seme.

' Claim. Not confining myself to any speeialmaterial for constructing the seme, what I eluim as my invention in white-lead mixing und feeding, and desire to secure by Letterslatent of the United Sta-tes, i's- 1. The mixer, consisting of the tank C, the water-pipe K, thedischarge-pipe V, with its gauged enel: L; the revolving arms Gr G', hnving'the perpendicular blades H H H H H H, Sie., and the shaft E, all constructed substantially as and for the purpose set forth; and

2. Combining with the mixer the fee'der, having the revolving arms P PP and blades R R R, shaft S, the

stationary bladesv O O0 (I), and the gouge-cock L', constructed and operating substantially as and for the purpose set forth'.
